MIXING-MACHINE FOR MAYONNASE.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application lefl September 27, 1912. Serial No. 722,678.

To all whom it may concern Be it known that l, JOHN lianes, a citizen of the United States of America, residing in New Rochelle, in the county of 1Westchester and State of New Yorlr, have invented certain new and useful Improvements in Mixing-Machines for Mayonnaise, of which the following is a specification.

rlhis invention relates to an improved machine for mixing mayonnaise, sauces and other culinary preparations.

Mayonnaise for salads was heretofore prepared by hand. ln large restaurants and hotels this involves considerable hard work as large quantities of mayonnaise have to be prepared.

The object of this invention is to furnish for household as well as restaurant and hotel use an improved machine by which mayonmuse,

sauces and similar preparations can be quickly and effectively mixed with comaratively little labor and effort, and in be readily detached and removed for being cleaned after use; and for this purpose the invention consists of a mixing-machine for Vmayonnaise which comprises a mixing-vessel having a hinged lid, a hollow upright center-shaft supported in said vessel Vand provided with radial rotating agitators and Scrapers, means for imparting rotary motion to the shaft, agitators and'scrapers, an oil-containing vessel supported on the lid and provided with a discharge-nozzle, communicating with the hollow shaft, a valve for opening or closing said discharge-nozzle for supplying the oil or other liquid to the shaft, and dischargeopenings in lower portion of said hollow shaft; the invention consists further of certain details of construction which will be fully described hereinafter and finally pointed out in the claims.

ln the accompanying drawing, Figure l represents a side-elevation of my improved Vmixing-machine for mayonnaise, Fig. 2 is a vertical central section through the same, Fig. 3 is a plan-view, partly in horizontal section, on line 8, 3, Fig. 2,.Fig. l is a detail section through the oil-supplying vessel, showing the connection with the hollow shaft of the mixing devices, and Fig. 5 is a section through the lower part of the mixing vessel, showingthe rotary Scrapers in the same. i

Similar letters Vof reference indicate corresponding parts throughout the several iigures of the drawing. y Y Referring to the drawing, a represents a mixing-vessel of cylindrical shape, which is closed tightly at the lower end by a metallic botom al having a circumferential flange a2. `hc cylindrical vessel a is reinforced at the upper end by an exterior band a3 of sheetmetal and provided with recesses r in the upper portion of the same vessel and band, located at diametrically-opposite points, for supporting the ends or gudgeons 01 of the diametrical supporting-frame c. A drivingshaft Z is supported in'bearings Z1 attached to the supporting-frame c. The outer end of the driving-shaft Z is provided with a crank-handle (Z2 and its inner end with a bevel gear-wheel c which meshes with a bevel gear-wheel el on the hollow vertical centershaft s of the machine. The shaft s turns in a step-bearing s1 on the bottom of the mixing-vessel a and in a neck-bearing s2 0n the diametrical frame c. The step-bearing s1 for the shaft s consists of a bushing havingV a square socket into which fits the correspondingly-shaped hub of a bevel gearwheel y in which the shouldered end of the shaft s is rotated. The bevel gear-wheel g .is placed in mesh with two bevel-pinions g1 on aV diametrical shaft s3 which passes transversely through a hole in the lower solid portion of the upright hollow shaft si", said shaft being provided with agitators or mixers f, f1 that are placed at right angles or any other suitable angle to each other on the shaft s1 so as to agitata the ingredients to be mixed.- The agitators f, f1 are attached in any suitable manner to the horizontal shaft s3. The agitators are rotated by the planetary bevel gearing g, g1 around the Vupright Vshaft s when the same is rotated by the crank-shaft and bevel gear-wheels actuated thereby. Immediately above the shaft s3 are Yarranged two stationary radial arms h to which are applied scrapers h1 that extend in downward direction so as to formV contact withV the bottom and side wall of the vessel,said scraper-s moving along the bottom and inner surface of the wall of the mixing-vessel for scraping off the mixture placed in the mixing-vessel and throwing it inwardly into the path of the agitators for being thoroughly beaten up and mixed by the same. Immediately above the radial lscraper'- carrying arms are arranged two inclined holes o, which are located at diametricallyopposite sides of the shaft and above the lower solid portion 'of the same, said holes communicating with the interior hollow center-shaft and supplies the olive-oil or other liquid to be mixed with the ingredients in the vmixing vessel. The oil or other liquid is supplied from an oil-receiver p which is attached to the hinged lidr Z of the mixing-vessel. The oil-receiver is provided with a filling-opening 01 in its toppart and a sliding plate o2 for closing the opening after the oil-receiver has been iilled with oil. The oil-receiver y) is provided at its lower part with a tubular nozzle 721, having a tapering end which is seated in the upper end p2 of the upright tubular shaft s, while a collar m surrounding the nozzle forms a tight closure with the shaft. At the inside of the nozzle is arranged a valveseat n, sothat the nozzle can be closed by screwingr down la valve nl, which is operated by a stem n2 that passes through a stutlingbox in the top ofthe oil-receiver, the stem of the valve being located in a cylindrical sleeve n3 which is integral with the bottom of the oil-receiver, and which is provided with an outlet-opening o3 for the oil, near the bottom of the oil-receiver. As soon as the valve nl is raised, the oil flows through the opening o and nozzle n and hollow shaft s and through the outlet-open-v ings o in the lower portion of the shaft, above the scraper-arms, into the mixingreceptacle, and is there mixed with the other ingredientsfor making mayonnaise, sauce or other semi-liquid or pasty mixture. As soon as the required amount of oil is supplied, the discharge nozzle is closed 'by screwing down the valve and the agitators and Scrapers operated for producing the thorough intermingling of the ingreclients.

The mixing-vessel, the lid and the body ofthe oil-receiver are preferably made of glass, porcelainor similar material. rl`he upper end or rim ofthe mixing-vessel is reinforced by the sheet-metal band a3, to which thelid is hinged on which the oilreceiver is supported.

The improved mayonnaise-mixer is used as follows: The oil-receiver is viirst supplied with the required quantity of olive-oil, or other. suitable liquid, that is to be mixed with the other ingredients which are placed into the mixing-vessel. The required quan- 'tityof oil is then delivered into thefmixingvessel and the valve oi the oil-supply nozzle* closed. The ingredients in the mixingvessel are then agitated by the rotary agitators and'scrapers, until the proper intermingling of the ingredients with .the oil or other liquid is obtained; after a certain time vanother quantity of oil is supplied and the valve again closed and thermixing operation repeated until the mayonnaise is inA proper condition for use when itis removed and ready for use.

The mixer is made up in different sizes, the smaller size being for family use, the larger sizes for hotel and restaurant use. The lid is made of heavy plate-glass so as to close the mixing-vessel tightly by its own weight.

in i lace of ma onnaise sauces and the v i, K

like, the .mixing-vessel can also be used for" beating up eggs, making icing andtorother i semi-liquid mixtures, in which case the la`-. vering oils are placed in the oil-receiver and mixed with the sugar, eggs and other ingredien-ts placed in the mixing-vessel. The mixing of the ingredients is accomplished rapidly by turning the crank Aand quickly rotating the agitators and Scrapers, until the ingredients gled.

For removing the mayonnaise or other are thoroughly interminmixture, the lid is placed in open position with an outlet and with adjustable means for controlling said outlet, said tubular shaft being operative to receive oil from said container and discharge it in regulated quantities into said vessel in position for the action of said mixing device, and means for rotating said shaft.
